腰椎融合术后发生邻近节段椎间盘退变的系统评价

[目的]对腰椎融合术加速邻近节段椎间盘退变进行系统评价.[方法]按照Coehrane协作网制订的检索策略进行检索,计算机检索MEDLINE(1966～2010年8月)、EMBASE(1974～2010年8月)、Cochrane图书馆(2010年第8期)、中国生物医学文献数据库(CBM,1978～2010年8月)、中国期刊全文数据库(CNKI,1994～2010年8月)、中文科技期刊全文数据库(VIP,1989～2010年8月)及万方数据库(1979～2010年8月).手工检索相关的中英文骨科杂志和会议论文.纳入腰椎融合术后发生邻近节段椎间盘退变的所有临床试验,由2名评价员独立提取资料,并对其方法学质量进行评价.对符合纳入标准的研究用RevMan 5.0软件进行Meta分析.[结果]共纳入4个试验,451例患者.Meta分析结果显示:相对功能洲练(保守治疗)来说腰椎融合术后发生邻近节段椎问盘退变(adjacent segment disc degeneration,ASD)的概率增高[RR=0.63,95%CI(0.52,0.78)P<0.000 1];腰椎融合术中椎板切除后ASD发生率比不行椎板切除的高[RR=3.74,95%CI(0.99,14.18)P=0.05];腰椎融合术前存在ASD比术前无ASD在术后发生ASD的概率高[RR=3.13,95%CI(1.20,8.15)P=0.02];腰椎融合术后ASD的发生与是否有内固定和融合节段的多少无关.[结论]腰椎融合术能增加术后ASD的发生率,与椎板切除和术前就存在ASD有关,但与是否有内固定和融合节段的多少无关.限于纳入研究在方法学方面的局限性,尚需开展大样本、高质量的RCT进一步论证其疗效和安全性.

Anterior cervical foramenotomy for cervical radiculopathy

Anterior cervical discectomy (ACD) is standard practice for cervical radiculopathy. Irrespective of the precise method used, it involves more or less complete disc removal with resultant anatomical and biomechanical derangements, and frequently the insertion of a bone or prosthetic graft. Anterior cervical foramenotomy is an alternative procedure that allows effective anterior decompression of the nerve root and lateral spinal cord, whilst conserving the native disc, preserving normal anatomy and movement, and protecting against later degeneration at adjacent spaces as far as possible. The aim of the study was to determine the safety and efficacy of anterior cervical foramenotomy in the treatment of cervical radiculopathy and took the form of a prospective study of 21 cases under the care of a single surgeon. All patients had a single level or two level anterior cervical foramenotomy. All had pre- and postoperative visual analogue scores for arm and neck pain, arm strength, sensation and overall use. A comparison between patients' perceptions and surgeon's observations was also made. Patients were followed up for between 10 and 36 months. Sixty-eight per cent completed full pre- and postoperative assessments. Twenty-eight per cent of the responders had complete arm pain resolution. There were statistically significant reductions in arm and neck pain, and overall disability. The surgeon's impression of improvement paralleled that of the patients. There was one complication with discitis. Anterior cervical foramenotomy is a safe and effective treatment for cervical radiculopathy caused by posterolateral cervical disc prolapse or uncovertebral osteophyte, and might also reduce adjacent segment degeneration.     

Alternating cervical laminoplasty for cervical spondylotic myelopathy

We present a novel method of performing an 'open-door' cervical laminoplasty. The complete laminotomy is sited on alternate sides at successive levels, thereby allowing the posterior arch to be elevated to alternate sides. Foraminotomies can be carried out on either side to relieve root compression. The midline structures are preserved. We undertook this procedure in 23 elderly patients with a spondylotic myelopathy. Each was assessed clinically and radiologically before and after their operation. Follow-up was for a minimum of three years (mean 4.5 years; 3 to 7). Using the modified Japanese Orthopaedic Association scoring system, the mean pre-operative score was 8.1 (6 to 10), which improved post-operatively to a mean of 12.7 (11 to 14). The mean percentage improvement was 61% (50% to 85.7%) after three years. The canal/vertebral body ratio improved from a mean of 0.65 (0.33 to 0.73) pre-operatively to 0.94 (0.5 to 1.07) postoperatively. Alternating cervical laminoplasty can be performed safely in elderly patients with minimal morbidity and good results.     

微创前路经上位椎体椎间孔减压术治疗神经根型颈椎病

【摘要】 目的：探讨微创前路经上位椎体椎间孔减压术治疗神经根型颈椎病的有效性。方法：2008年7月~2010年7月12例单侧神经根型颈椎病患者在延边大学医院接受微创前路经上位椎体椎间孔减压术。其中男7例,女5例,年龄为35~68岁,平均49岁。椎间孔狭窄部位：C5/6 4例,C6/7 5例,C7/T1 3例。软性髓核突出3例,钩椎关节骨质增生7例,突出的髓核钙化2例。均行前路手术,术中采用脊柱手术专用显微镜,在病变上位椎体确定钻孔起始部位,利用高速钻石气钻磨出一约6mm直径的通路达到病变区域,减压椎间孔。观察术前及末次随访时上肢放射性疼痛的VAS评分、颈椎功能障碍指数（NDI）及病变水平椎间盘高度。结果：手术时间为56~110min,平均86±6min;术中失血量为40~120ml,平均92±8ml。无椎动脉损伤、贺纳氏综合征、喉返神经损伤等并发症。术后随访时间为12~23个月,平均15.8±1.3个月。术前上肢疼痛VAS评分为8.5±0.5分（7~10分）,末次随访时为1.4±0.2分（0~3分）,两者比较有显著性差异（P<0.05）;术前NDI为26.4±1.3分（22~31分）,末次随访时为4.2±0.6分（3~8分）,两者比较有显著性差异（P<0.05）,改善率为84.1%;术前病变水平椎间盘高度为5.4±0.7mm（4.2~6.1mm）,末次随访时为4.9±0.7mm（3.6~5.8mm）,两者比较无显著性差异（P>0.05）。术后满意度为100%。结论：微创前路经上位椎体椎间孔减压术可减少对椎间盘的损伤,是治疗单侧神经根型颈椎病的有效手术方法。     

Posterior cervical laminoplasty formultilevel cervical spine stenosis

Cervical laminoplasty for treating multilevel spinal stenosis appears to be a good surgical alternative to the more traditional laminectomy or anterior decompression and fusion. This procedure avoids the morbidity associated with extensive anterior procedures and also appears not to be associated with late kyphosis, which can be seen in patients after a laminectomy. This review outlines the rationale, indications, contraindications, and early clinical results for patients undergoing a posterior laminoplasty.     

Anterior cervical microforaminotomy for cervical radiculopathy--results and review

Analysis of anterior cervical microforaminotomy performed at the North Staffordshire University Hospital along with a review of literature of this minimally invasive procedure is presented. METHODS: A retrospective-prospective study was performed on 34 patients (24 males, 10 females) with cervical disc disease who had been surgically treated with anterior cervical microforaminotomy between 1999 and 2005. Age ranged from 37 to 75. MRI findings were disc prolapse in 28 and additional osteophytes in six. Microforaminotomy was performed according to the published technique. RESULTS: Single level operations were performed in 22 patients (21 unilateral, 1 bilateral) and multi-level operations were performed in 12 patients (7 unilateral and 5 bilateral). The short-term outcomes were excellent in 65% (i.e., complete resolution of all symptoms), good in 29% (relief of radiculopathy but some non-radicular discomfort persists), and fair in 6% (mild residual radiculopathy with or without non-radicular symptoms). Postoperative complications include one patient with partial C6 root damage, which was identified intraoperatively, but had excellent results at 2 months post operation. Long-term follow-up (using the cervical spine research society questionnaire) ranged from 2-48 months. The average pain score, neurological outcome and functional outcome improved after this operation. RE-OPERATION: One patient, who had 2 level bilateral surgeries, needed discectomies with fusion for new onset myelopathy 18 months later. CONCLUSION: Appropriate patient selection is cardinal in achieving good outcome in anterior microforaminotomy.     

Postoperative instability of cervical OPLL and cervical radiculomyelopathy

The presence of cervical spine instability with respect to preoperative and postoperative changes in angular, horizontal, and rotational displacement of the vertebral body were studied. With the anterior approach, the instability in the remaining unfused segments, and their relation to the kyphotic or lordotic fused segment were studied. With the posterior approach, postoperative ROM (range of motion) could be better maintained, and horizontal displacement was improved in more cases by laminoplasty compared with laminectomy. With the anterior approach, the compensatory function for the loss of motion of the segments resulting from fusion was most remarkable at the levels of C2-3 and C6-7. In the alignment of the anterior fused segments, it appears important that the physiologic lordotic position be maintained.
